Usually I'm very...frugal when it comes to buying rolling stock. I don't think I have EVER paid more than $20 for a car...that is until recently. Currently the two most expensive cars I have bought are the Bluford SP transfer caboose ($28 online plus shipping) and the MT SP impact car ($48 online plus shipping). I did wait too long to buy the two car pack of Chateau Martin reefers from NSE (while I don't drink wine, there were more than a few wine tanks and reefers on the RR I model as well as in the area I live). I have noone to blame but me since they came out with three different pairs, but at $81 a pair, I just couldn't pull the trigger. $40+ for just a 'standard' MT reefer, but now I'm starting to wish I had bought at least one pair. With seeing how some MT cars have gone for $100's and even on occasion $1000's of dollars, I started wondering: Whats the most expensive piece of rolling stock you have bought and why?
