How long do you plan on keeping it? How do you plan on using it? If for many years and cruising/pleasure driving only, go with the base with 11,500 miles. At that mileage, it is barely broken in. The base will be less expensive to keep up (tires, brakes to name a few). Both have the LS3 engine and the base will be a little faster (GS weighs more) if they are both stock without any mods. Probably doesn’t mean anything. If you are going to mod it, track it or auto cross, then the GS would be a better option. The condition, maintenance history and number of owners should be taken into consideration when determining how much you are willing to pay.

Remember if the tires are old you will have to replace them.

GS especially if it’s a manual. You have a put a lot of money into a base to make it widebody and dry sump. Not to mention all of the other benefits.

I’d choose this one, but not at this price. It’s a buy at $28,500.

The GS has average miles at best, and with them both being autotragic, no hand-built dry sump to brag about.

OP says automatic.

I would go GS. Try to negotiate a better price. Good luck

Grand Sport hands down. The wide body and suspension/brakes are a no brainer. I also agree that a 2010 should go closer to the 28500- 29500 range. Good luck!

...and to get more confused by. Whenever you compare two different cars, you will always jump back and forth between them. Maybe start making them more reasonably priced offers, and whichever one takes it, then bingo! I don’t envy your decision, as both cars have good points about them. It just matters what is more important to you!

Good luck,
