Too much maintenance = new car?

A while ago I was back and forth about getting a new car. With 188000 miles, and $2500 in maintenance costs, hmmm...well...
Nah, just kidding...it's a loaner. So I call this place, which will remain nameless, to get a quote for some service on my truck. I needed a major service (air filter, oil change, spark plugs and wires, coolant flush, lube diff and door hinges), timing belt replaced, and a brake job. The quote sounded reasonable and they said they can do it in a day. Cool, so I make an appt. a week in advance. Brought it in the morning early bird drop off...these guys don't open till 9:30am. Get a call early afternoon, "Uhh, a part we ordered won't be here until late, so we won't be done till tomorrow afternoon...". Hmm, fine, take your time, get it done right, and give me a loaner. Thinking I'll get some beat up old Ford Fiesta, the guy brings me out to an RX8...cool. Haven't opened her up yet, but will let you guys know... As for a new car, I think I'll stick to my Montero for a while. I like not having car payments.
