I'm actually yawning while I type, sorry it it puts you to sleep but it's a valid one (I think)
I've never filled up my Subaru, it's a 96 JDM STI, how big is the tank?
I am actually quite an economical driver, My C2GT gets 47mph, I drove from Guildford to Crewe on 1 tank of fuel in my FD3S RX7 and I drove the Subaru from Brighton to Guildford and back on less than £20.
I have an exhaust, de-cat, filter and FMIC, the rest I think is standard.
My reason for asking is I'm already planning my return to Chamonix (I've not left yet) and thinking a weeks holiday down here during the summer, drive down with the Subaru and enjoy some mountain passes and tunnel runs
It's just under 700 miles door to door.
