Saw that Red one earlier this week, turned off by the LPG comments.
Think this one is better bet. Easily fixed issues and a steal.

If you can get a late 1998 with GEMS engine I think you might be safer on liner issues. There was fairly major revision in 1997 where they sorted a lot of niggles out and then in 1999 they changed again with the introduction of Thor engine and 4W traction control.
