Purchase advice E38 740i 12/98 Facelift 130000km 1500€

Hello together, I am thinking of buying a BMW 740i E38. It is a private sale with 130,000 km, very good equipment, and the vehicle is a first possession of an older gentleman who unfortunately died. The son (about 60 years old) sells the car now. A few details: • Service booklet: Not complete, but all repairs were probably made at BMW. • Damage: The vehicle once had a sheet metal damage at the rear left. • TÜV: According to the seller, the vehicle is in the l TÜV-report “without defects” registered (valid until 2026), however, a slight defect due to oil moisture was previously found at the TÜV. The seller thinks that the car had been driven for a while. • Rust: allegedly stainless. • Electrics: The starter and the electronics were replaced twice, as well as the battery, but the car sometimes only starts with the second attempt. In addition, the seller sent me all invoices by video. Unfortunately, many d avon hard to read, which is why I can’t give you exact details. However, I can upload photos from the service booklet and a larger repair if that helps. I have some concern that the engine might have been damaged due to the non-stop maintenance or oil moisture. In addition, I would have to drive about 800 km to get the vehicle, which does not make the decision easier. What do you think, professionals? Would you buy or rather leave your fingers off it? nk for your help and tips! LG and thank you in advance!
