Whoever said that they wanted a Maserati, you're wasting your money. If you think the C6 Corvette is ugly then something is wrong with your eyes, a lot of great engines came from that era.
The C7 Corvette is actually one of the best cars you can find a fully loaded(which is the 3LT, the 4LT is a waste of money)used for around $40k-$45k. The LT1 is a lower compression version of the LS3, meaning it's great for boost but not necessarily great for what the LS3 was great for. I personally think the LS3 is better but you can't really go wrong with either one.
It weighs in at around 3200-3300 lbs and runs flat 12's in the 1/4 mile. 0-60 times don't mean anything so don't let advertisers fool you, 1/4 times tell a lot about a car. A car weighing that much is highly desirable in today's market as well.
Depending if you go automatic or manual, the MPG will fluctuate. Automatic uses something called Active Fuel Management(AFM) which essentially shuts half your engine off, making it run on 4 cyl, to get better gas.
Manual versions have a button for active rev matching making your shifts perfect every single time.
The issue with AFM is that it will decide to automatically shut half your engine off for you. If you plan on changing your exhaust, the changing from v8 to 4cyl will be noticeable and it will not sound pleasant. You do get better gas MPG. There are devices that you can put into your OBDII port to temporarily disable it without voiding your warranty though.
Insurance is actually really cheap. It's cheaper than paying for a Camaro in comparison. Part costs are similar to the Camaro, not necessarily expensive for a performance car. But body parts and suspension parts are blatantly more expensive- and rightfully so. If you don't plan on spending $275+ per tire then this is not the car for you.
Corvettes are designed to be a drivers car and the interior reflects this very aggressively.
But I don't think you should limit your options there. There are great cars for similar price if not cheaper. The C63 AMG and the E90/E92 M3's come to my mind immediately. If I was willing to drop $40k, I'd probably just save up another $20k for a Nissan GTR.
