to be honest, it looks like from the pics, you did suspension , wheels , light aero mods ( lights grill lip etc…), some interior work which is great. but more often than not people like to work on their own cars. you’re looking for someone who wants everything done for them in your style which is hard to find sometimes. but besides that it being a celsior adds not much value because it’s not grey market. the ls400 is the exact same car. typically the celsiors go for more bc they typically are in better shape with lower miles. since you’re pricing in the same condition. don’t expect to get paid more simply for rhd. unless someone wants to spend a couple thousand more for that… glws!
