CAMPBELL, Judge.
Core's automobile liability insurance policy insured only two named vehicles, a 1961 Oldsmobile and a 1960 Plymouth. That policy did provide, however, that automatic coverage would be extended to a newly-acquired vehicle if it replaced an owned automobile covered by the policy.
Judge Canaday made the following pertinent findings of fact:
1. That Core's insurance policy issued by Aetna was in full force and effect on 27 June 1970 on which date Core acquired the 1966 Mercury automobile not owned by him prior thereto.
2. That on 30 September 1970, the date of the accident involving the 1966 Mercury, the Aetna policy was in full force and effect.
3. That on 27 June 1970, while on an emergency trip to Duke Hospital in Durham, North Carolina, the 1961 Oldsmobile emergency vehicle developed mechanical trouble and that Core telephoned his wife and instructed her to purchase the 1966 Mercury.
4. Upon his return from Durham, Core and his wife removed all of the medical supplies and emergency equipment from the 1961 Oldsmobile and transferred that equipment to the newly-acquired 1966 Mercury.
*56 5. That the 1961 Oldsmobile was placed in a shed at the rear of the Core property and was never moved from its position under the shed until after the accident, at which time it was repaired.
6. That Mr. Core occasionally started the engine of the 1961 Oldsmobile, but eventually the battery went dead; that for one period, Mr. Core spread peanuts in the back of the Oldsmobile to dry; that grass grew up around the vehicle.
7. That Core removed the license tag from the 1961 Oldsmobile and placed it on the 1960 Plymouth; at the same time he removed the license tag from the 1960 Plymouth and placed it on the newly-acquired 1966 Mercury.
8. That Core intended ultimately to dispose of the 1960 Plymouth after he repaired the Oldsmobile, which then would be used as a backup ambulance to the 1966 Mercury.
9. That on 4 September 1970 an employee of the North Carolina Department of Health inspected the ambulances of Dunn Ambulance Service and certified as operable and approved for use the 1960 Plymouth and the 1966 Mercury; the 1961 Oldsmobile was indicated "not in service".
Judge Canaday then concluded that the 1966 Mercury was a newly-acquired vehicle which replaced an owned automobile covered by the Aetna insurance policy, and that inasmuch as the 1966 Mercury was acquired to replace an owned automobile covered by the policy, Core was not required by the terms of the policy to notify Aetna of its acquisition.
There is ample evidence of a competent nature to support the findings of fact of the trial court. If the trial judge's findings are supported by competent evidence, such findings are as conclusive as the verdict of a jury. They are binding on this Court. Insurance Co. v. Shaffer, 250 N.C. 45, 108 S.E.2d 49 (1959). Whether the newly-acquired Mercury was a replacement vehicle within the meaning of the liability insurance policy is a mixed question of law and fact and is to be settled with the interpretation of the insurance policy in light of the facts found.
In the Shaffer case our Supreme Court defined a "replacement" vehicle: A replacement vehicle must be (1) acquired after the issuance of the policy on the named vehicle, (2) and during the policy period, and (3) it must replace the vehicle described in the policy (4) which must be disposed of or be incapable of further service at the time of the replacement.
In the instant case the evidence supports the finding that (1) the 1966 Mercury was acquired after the issuance of the Aetna policy; (2) the Mercury was acquired during the policy period; (3) after the Mercury was acquired it was operated to the exclusion of the 1961 Oldsmobile.
The question determinative of this appeal, then, is, what is the meaning of the term "incapable of further service?"
The appellees contend that the term means "out of repair and not fit to be driven at the time"; "not operable at the time". Insurance Co. v. McGhee, 292 F. Supp. 176 (W.D.Va.1968); Lynam v. Assurance Corporation, 218 F.Supp. 383 (D. Del.1963).
The appellants on the other hand, contend that the term means "not operable at the time and for practical purposes cannot be rendered operable". Nationwide Farmers Union Property and Casualty Co. v. Nyborg, 290 Minn. 191, 186 N.W.2d 702 (1971); Nationwide Insurance Co. v. Ervin, 87 Ill.App.2d 432, 231 N.E.2d 112 (1967).
In formulating its rule that a replacement vehicle must replace one which is "incapable of further service", the Shaffer opinion of our Court cited Casualty Co. v. Lambert, 90 N.H. 507, 11 A.2d 361 (1940). The rule itself as enunciated in Shaffer, and upon review of the facts in Lambert, clearly indicates that the insured need not dispose of title or control over the replaced vehicle.
In Lambert the defendant's automobile was retained by him, parked in a garage, *57 and although never driven, it was licensed for operation in the defendant's name. The court held that the new vehicle was intended to be a replacement, and was so regardless of whether defendant retained possession of the old automobile.
Core, in his business, never used more than two ambulances and was not equipped to do so. One ambulance was used as a backup vehicle for the other.
The evidence in the instant case clearly indicates that the 1961 Oldsmobile and the 1966 Mercury were not capable of being used simultaneously and were not intended to be. The Mercury was in fact driven exclusively and the Plymouth remained the backup vehicle as it had been before the Oldsmobile was removed from service. Use of the 1961 Oldsmobile was abandoned; and abandonment of use due to inoperative condition of the vehicle, we feel, is sufficient to establish the relationship of replacement vehicle. The possible exposure of Aetna remained the same at all times.
No error.
