You're not 'investing' in snowboarding kit, you're spending money on snowboarding kit.

On the up-side you'll be spending well under half on fuel vs what you would have been with the V6 motors.
On the down-side you've bought the wrong diesel. 50MPG TDI Golf3, Passat, Vento, Seat or Skoda would have been a much better choice - more poke and economy probably around the same.
