Nice idea! I do want to unroll/unstretch the rear arches, but I suspect that'll be a cut them out and attach new ones job.
Economy. 1155.6km on less than 75 litres of fuel. That's less than 6.5 litres per 100km, making it cheaper to run than the 320d (once RUCs, extra rego and suchlike are taken into account). Doesn't have the same performance, power or torque, of course. All the same, seriously tempted to find an E46 1.8/1.9 (M43) Touring.
