Just topped 20k into my car in 3 years (including the 6k purchase price). Almost all (except maybe 2k) is body and paint. I like new parts where I can.. and they are hella expensive and my mechanic abilities aren't up to par for me to trust myself doing the engine work.
A lot of people assume that a car like this is overexpensive. I dont think that. ANY car is a waste of money unless you have a classic car worth 60,000+ and can afford to store it in a humidty controlled storage area.. and at that point.. you probably arent someone who has to worry about money anyway. Also I think in about 5 years, the market for these cars will change quite a bit as people start collecting more Japanese/Euro cars (face it.. the classic US car crew is retiring.. lol). The kids that grow up in the "fast and the furious" age will have Supra stamped in their brain and the cars are dying quicker than being revived.
For repair costs.. bear in mind.. the brakes on a 1999 Chrysler 300M (17") cost over 650.00 in parts if you cheap out. You dont even want to look at repair costs on the newer vehicles when the engine dies prematurely or the automagic transmission with additional faux-shifing starts acting wonky. And good rims and tires can be done on a budget.. but proper ones are NOT cheap... and.. who wants a cheap Supra?
The real problem is, the car is undervalued because repairs are usually VERY intensive and VERY expensive (2 words that will crater most "hobbiests"). I could have bought a MKIV and been further ahead, however, I really dont like the look of them although the ride is much better. The MKIII is very unique and I personally can just stand outside and stare at it. Its like Opium.
Nothing cheap on the car except the selling price..
I researched the car for 2 years before buying (should have researched 4... ) and planned on putting roughly 36,000 into it when done. No disappointment here
Worth it? logically no.. emotionally ... very.
Oh forgot to mention.. my car is insured as a Collector's car.. I dont know about other areas, but in Alberta this is already classified as an antique.
