Thinking back I wrote my post above from the perspective of a pensioner - capital rich ( in a small way!) and income poor. If you have a six figure income or can put the new car through your business without borrowing then I dont see the worry about losing 10k or 20k. You can replace the capital. You cant do that with the active years you lose waiting until Aero prices are lower.
So if thats the case - go for it!.
