Hothouse was available on V2 and V2II, so it was around from 2001, but not sure where else. It wasn't a colour for VUII as the ugly hero colour in that was Hyper (metallic poo yellow). It was definitely around in VY as Innuendo says (which is the same timeframe as V2II). When I bought my Quicksilver V2 CV8 in Feb 2006 I could have had my choice of V2 CV8's in Hothouse like $5-$10k cheaper, no-one wanted them. The guy that bought my VY SS ute had a Hothouse VY V6 S ute, couldn't sell it or trade it, ended up virtually giving it away (like at half what he paid for it). I remember Cosmo with Cosmo trim! When I was looking for a CV8 there was a V2III Cosmo/Cosmo CV8 traded at the local Lexus dealer, fantastic car less than 12months since bought new with like 5,000kM on it or something like that. It was only about $2000 more than the V2 I bought with 28,000kM on it. Yuk! If it was Cosmo with black trim i'd probably have bought it, but the purple trim was disgusting to say the least!
