Don't even hesitate to do it. I have had a gen. I, II, and now III. The III is so much better in driveability and seating position and easier to drive fast that it ain't even FUNNY!! NOW that I've said that, beware of any 2005 that is out of warranty. It must have a factory warranty unless you personally know both the previous owner and its driver. I traded mine to one of the Big Four dealerships for an '05 that had been a DC Exec. car, still in DC's name and inventory. I checked the history by carfax and nothing showed of a negative nature. Not everything gets reported, it seems. Eight months later my warrantied engine is in the shop for a complete rebuild and this is what was found: spun 3rd rod bearing from G-forces in turns while apparently being raced, overheated engine (stuck gaskets to valve covers and oil cover), and cam bearing service bulletin upgrade (never reported to me by carfax), clutch was 80% gone, with hotspots, and the same for the flywheel, and yet the engine/car had only 17K miles on it when it failed (10K when I bought it). The car looked great and run only a little sluggishcompared to my '96 Tradein, which had an alum. flywheel, VEC1, 3" exhausts and Borla mufflers, trick clutch, SVS shifter, etc, and after 49K miles it would FLY! I thought: the gen. III seems sluggish because it's unmodified. Now I now "THE REST OF THE STORY." The good news is that the gen. III engine is being rebuilt to higher specs than original, with the origninal block, as they were able to save the block-though all internals are NEW and will be thoroughly dyno tested. Moral: it's a good trade if you have factory warranty. I'm still Glad I traded, but maybe better off if I had chosen a different car. But how could I have suspected that? No carfax warning, and the car looked nice. Still, all's well that ends well. Good luck to you.
