I just wanted to send a testimony to my 1994 Diamante Wagon. I have driven it for the last five years with only routine maintenance. The 'ol girl has 265,000 miles on it, and I just replaced the timing belt...hoping to get to 300,000 and beyond. A joy to drive!
I have never had so much mechanical trouble with a car like I have had with the Mitsubishi. This car has given me so much heartache and expense. I have taken good care of it but the motor, transmission, and compressor still went out!!! And yes, the warranty just ended at 75,000..But I kept driving it because it was paid for, but it has had it's time in the shops!! My brother got him Mits. and had the same trouble and turned it in within a year. I will NEVER buy a Mits. again. AND I have told very many people about the bad experiences that I have had. I do not want anyone to go thru what I went thru with the expense in repairs.
Best car I ever owned until the warranty ran out... then, new steering assembly ($1500). Electrical problems out the wazoo. The coup de gras, engine blew due to defective cam shaft,and I change the oil every 2000 miles, like an idiot, and this car made feel like one. I spent another $1800 to fix the engine, but they couldn't put Humpty togather again. I sold it to my neighbor for $600 and begged him not to buy it. Now the his grass is growing around it. He thought he could fix it, but 1 year later it still sits. Mitsubishi, fool me once, shame on you.
Apparently there are about 85 of these in the Bay Area (out of 5M cars...). This was the most comfortable wagon, with the best ergonomics, space, and setup. Extremely comfortable for me (6'5") and the whole family. The problem with this car: the engines just suck. At about 85,000 miles this car started developing all sorts of problems (leaks in the block, for example) and mechanics reported that this is not uncommon. Traded this car, sadly, for a Subaru.
Overall it's been a great car that hasn't let us down. Some weak point on the car is its oil consumption with age and the life of the brakes before they "wobble". Both items are known in the Diamante community and there are ways to combat them, but they are out there as issues. Otherwise, pretty good car for the price.
