There were a few Hot Wheels Suburbans back in the 90's/early 2000s, I think I've got all of them now. There was a four piece set with different NASCAR themes, plus a "Walker Racing" 'burb from a separate promotional set that I believe was sold at race tracks around the country IIRC. Also a "Team Baurtwell" edition, the standard one was red but there's a blue chase variant that was limited to 30K pieces. Can't find any pictures of my blue one so I grabbed one off of Google.

I also have one of the Brookfield models mentioned earlier, mine is one of the non-NASCAR versions that seem a little less common. Two tone blue and silver.
