If you're considering buying a 1948 Packard, you should keep a few things in mind. First, getting the car on a lift is important to check for any rust or damage. The frame, floorboards, and trunk should be in good condition with no rust. The quarter panels and fenders may not have been repaired, so check for rust. The interior is mostly intact, but it may be an older restoration. Mohair upholstery is often used in older cars, so that's not necessarily a negative. I would be cautious about buying a car from a dealer without a warranty or guarantee. Make sure you test drive the car and have a mechanic inspect it before you make a purchase. I did the same when I found a skyline for sale, and I think I will buy it next week. Good luck!
