I have an 89 240 we bought new (same as a 90 except airbag), and it absoulutely has been the best car we have ever owned. May not be the latest styling but they are extremely tough solid cars. Ours has 140k miles and has never let us down, starts and goes every time. I am currently averaging about 20k miles a year and plan on keeping it for several more years. I would feel completely comfortable taking off on a cross country trip in it. But that being said, routine maintenance is very important to avoid costly repairs. You should probably figure on about $500 annually for upkeep- minor repairs (you can do a lot of them yourself), tires, battery, shocks, etc. I am amazed at the network to support keeping these cars running- this website, aftermarket suppliers like the advertisers on this board. I would recommend to have it checked out by an independent mechanic that knows 240s. Check under the car for oil leaks (my biggest headache), including the plastic screens on the bell housing at the rear of the engine. If you find oil coming out here the rear main seal is no good, which is an expensive repair. Also check out the A/C which can be expensive to repair. The engine should last forever if it has been properly maintained. Good luck.
