I'm not sure what I would do in your situation. If I had the space & the money to keep all of those cars, I think I would do just that. I think I would sell the Accord and the parts cars, and get something AWD capable if I was in your situation. But I have my Honda (fun car) and my AWD (Toyota)... I only want to keep both running for as long as I can, and give both of them engine swaps for more power.

Edit: I mean that I would get an AWD car if I had the cars you have... well, I think you have an RT-4WD Wagon... so maybe not, lol.
