I am in the same boat. I really like the Solstice, and I think that the Ecotec powerplant was designed pretty well. GM also supports performance modifications of the Ecotec, and I would check that out before thinking that the 2.4 non turboed car is not what you are looking for.
What I do not like and that has been keeping me from getting one:
1) The advertised price versus what the dealers are offering. I do not care for nor will buy one with the premiums the dealers are selling them for. I do not understand how GM plans to build a loyal following by making a car I ould like to buy, and not having enough control over their supply chain to manufacture enough of them and to sell them at the list price at the dealer. I got the feeling I got one of these when I left the dealer
I am in my low 30's and would have paid cash.
2) I am curious about the quality/robustness in a year or two. I have never been accused of treating a car well, and so I want to see what problems pop up after these have been on the road for a year or two. My daily driver is a '99 Passat turbo, and this car has been great owned since new, sees the redline regularly, and has 180K miles and runs like a champ. I am having a hrad time looking for a new car because this one treats me well and the payments are great!
My wife has an '02 Grand Am with alf of the mileage, and I am putting a net on the back of to catch all of the parts that are falling off of it. Really dumb but very irritating items, too. Passenger window track BROKE ($200 in parts alone), computer goes apeshit sometimes when you back the car up - Dealer and 2 separate shops are unable to determine the root cause, and the anti theft has turned into an anti start twice, requiring a mechanic to drive to her location after shopping trips and reset it. Objectively, the car has a lot of power and drives well, but the devil is in the details, and I think the General did too much cost cutting on this platform.
3) For a daily driver, I have a small concern (non-existent if #1 & #2 were positives) with the amount of space. The local dealer would not take the time to open the trnk of one that was waiting for customer pickup, and I have to admit, '99 family car of the year has been quite handy when I am too lazy to go home and get the pickup. I have had 10 bails of shavings in the car, and 5 full sized adults car fit comfortably in it.
Long post, but I looked at these cars for a while and was very interested. I am now only Luke warm, and figure it may be a good future project once I get the 914 off og the jackstands.
