Thanks, I've currently got an EL 340,000+km and my LPG fuel economy isn't much better than that. I'm debating whether to go for an XR8 or the XR6T? I travel 140km round trip to work every day and tow an enclosed motorbike trailer interstate to go 125GP racing. The trailer weighs about 500-600kg fully loaded so its not heavy but its over long distances, eg; adelaide to vic, nsw and qld. would the XR6T have any problems with this?
