I'm pretty sure we've had a topic like this before but I can't find it, anyway no harm in having a fresh one for newer members. We all have that one model (or maybe even two or three) in our collection that we have a soft spot for.
For me, it's the resin New Holland TG285 that was only given to NH dealers at a meeting in 2002, 800 were made. Having been a big Ford fan, most of the modern NHs had left me fairly unimpressed but this really caught my attention and helped to reignite my interest. Ended up paying about €200 for one on eBay but delighted to have done so
