I got my Redline in Fall 2015. I have not had to deal with the water pump yet, but... Mine has fender cracks from improper lifting but I only found the evidence when I took mine apart and now I have lift "biscuits" to help address that issue. Sky Redlines are the way to go in my book, equiv to Sol GXP but more styling. Carbon Flash is great; beyond that, Sky has only a couple lim ed compared to the Sols. My wife would really love a Ruby lim ed... Avg Redline price can be 15 -20K depending on mileage and location. Base models are cheaper, and there can be a few very low mileage outliers to ignore. Redline equivalent is Sol GXP. There were more of those made, so sometimes style options, but they're not Skys in the style dept. Even there, with both, look at the function of either; style can be modified, but swapping Sky for Sol panels is more than I'd do... :smile:CHECK those fenders for Cracks. To me this is a bigger issue than the water pump. The only real way to see the cracks is get down on the ground, the cracking happens so far under it's impossible to see while standing (if you see while standing its a big crack) I did not know how far under to look when I got my car, lucky things worked out for me. But a cracked fender is a $1000 repair. I think Water pump is in the $600 range (someone else can tell you better on that one).
550 and that call that rare.. Ha.
Personally I hate the wheels but thats a personal taste issue. Now I have to question why the replaced the wheels a week before putting it up for sale? CHECK THE FENDERS FOR CRACKS.
Price 2008 redline 45k miles $12-$15k.
The other thing I would check on the 2008, is does it have the Electric vacuum pump (EVP) for the brake. Follow the line coming off the brake booser, if it T's within say a foot of the brake booster you have a latter one with with EVP if not its an earlier 2008 with no EVP. Is this an issue, I don't know as I never drove one without, but it would be a concern for me. Now if price is right and I love the car this would not be a deal breaker, just something to be aware of.
Oh and one last thing to check, CHECK THE FENDERS FOR CRACKS. oh, ask if they did an aftermarket tune to the engine or the GM powertrain tune (pic of the engine bay would tell us if they did the GM tune. Post some pics of the engine compartment.
