I'm actually working out a deal for some 14 inch alloys as we speak.
The posers hadn't put many miles on it, It was originally owned by some old guy (which explains the low mileage)
I would say 85% of the time is highway. My dad uses it for a 98 mile round trip commute monday-friday. The speed limit for my dads commute is 70mph, most people go at least 75mph, so he does too, to avoid death. When I drive it's 45-60mph most of the time with 10% 30-40mph.
I think aero mods will yield the best results.

i'd also like to make a kammback and side skirts similar to AndrewJ's
