Hi Steve. I haven't had any issues since I got the car except for a front Oxygen Sensor (under $150, oxygensensors.com FTW). Sucks about your transfer case, you've had yours about the same amount of time as I've had mine, less than 2 years. Did you get a warranty with the car? If not are you planning a rebuild or replacement? I haven't looked at local prices but I'd imagine a rebuild would be in a similar price range to a second hand used unit for replacement.
My wagon has seen much action recently, I bought a 1985 AW11 Toyota MR2 for a daily driver/track hack combo. It saves me a stupid amount of money in gas (2.5K a year after expenses). I just got a reasonable list WOF repairs ($1.5k for a shop to do) which ended up only costing me $40 and a box of speights
So now my wagon is a bit of a garage queen getting polished fairly fequently, it gets let out most weekends.
