Maintenance etc will obviously be higher, also the fact that your only looking for a daily..
but on the other hand it seems like you want the 32.. in that case you can just find one that's clean, get it checked by a mechanic (one that knows what they are looking at) and get a leak down, compression test done... will tell you the condition of the engine.. check for signs of wear, abuse.. you'll find a nice one for the price you get a GTT for..
i'd go for the GTR but only cause it looks like thats what you really want
