Which car? New construction as a hobby with subsequent sale

Hello together, I’ve been thinking for 1 year already if I like to repair a car – newly build or – restore or – with motor conversion. To me and my knowledge, according to my own assessment 😉 – 21 years, no two left hands, ambitious but often impatient and huddly. – Electrical: good to very good (electronic training, 2 years of forklift prototype construction) – Motor mechanical: well (basic features and prenzip of an engine present, if it is all in all) – Motor mechanical: well (basic features and prenzip of an engine present gs goes into detail like: mixture ratio, required compression, injection times, bezin pressure, T-loader, general, engine tuning in general “uvm.” unfortunately I can not keep up.) Bodywork: well (welding, spatling, I can and am by far not a professional) if necessary.Laking: I would then let the paintr do others: like brakes, cooling system etc. should be no problem. Tool and equipment: good basic equipment on tools, pit (no lifting platform), No speci altool. Electrically everything you need right up to the OZI. No software or hardware for the control unit to read or program. Buget and time: max. Buget 5,000€ can be less but likes to be less max. time 400pcs. / 1 year Now the questions of all questions – which car? as said this should only be a hobby, so no car what I want to drive afterwards. After the new setup / reperatur or restaration I want to sell the car again, then it would be nice of course if the So which car is now more value after the conversion? I drive a Mitsubishi Eclipse D30 which I have already put in money here and what I would get now with a sale for it, well you know what I mean. – First thought oldtimer, but I don’t like, bad spare parts supply, and goes right into the money. – direction Opel Claibra, spare parts, price, and plans no problem but de r is after a new construction none aways as much value as you put money in. – direction Camaro, again spare parts, price probably far over Buget. For tips, honors and car suggestions I would be very grateful to you. Greeting Franz
