I wouldn't give up on a T-Arrow, but I'd recommend finding one with a run-out engine. That way, you have a known-quantity and don't have to guess how it was abused in the past. If the original engine isn't an -FB, you might take a hit on the core credit. The intercooler and wastegate are good for that engine, but the 6 cyl Cont probably won't make TBO. So budgeta top at about 8-900 hrs.
The one thing about the 235 is the engine. Isn't is a 540 with the single-shaft/dual mag (PA31, TB20, 182RG)? That design never gave me a warm-fuzzy.
