p TRAVEL DE&j Bring A Car Back From Europe The greatest bargain in European travel this summer sum-mer could be the car you bring back home with you. It's an idea that's appealing appeal-ing to a growing number of Americans. How does it work? You buy or lease the car here for delivery in Europe. The savings sav-ings come from a combination combina-tion of price and not having to rent a car while you are there. Short-term rentals in Europe for cars in the price and comfort range of a Volvo average about SI, 500 a month. This bargain hint comes from Volvo of America Corporation Cor-poration which says that, with the exception of certain cer-tain special purpose vehicles, all 1983 models sold in the U.S. are available through the company's Tourist and Diplomat Sales Department.
