Car specs are here...
http://www.starmazda.com/cars.htm Costs are running in the high 30's - low 40's with full telemetry, ie MOTEC lamda... The Mazda 13B sealed crate motor is good for 3 seasons if maintained properly...
A good beater P/U truck and trailer about 8K... So, I figure 50K to get started... What the hell, worth looking into...
