Spikester...
My 182 I got 280 miles MAX to a full tank- was about 45ish then but on the up shot I chased Tiffs mate in his Chipped S3 and he wasn't pulling on me to an indicated 135- on a private test track!
On the down side the build quality is about as shite as I have ever experienced and selling it may prove difficult as theres about a million and yours prob wont have magnetised a branch of halfrauds to the rear end.
Ace car though- just make sure its got decent tyres or they dont turn in for shit!
