If it flies, floats, or fu***... rent it....
best advice ever and that is from someone that was a Porsche fleet customer at 21... payed
cash. It is not worth it especially in the current printing climate and flat renting offers...
Plenty of 3rd party (non sixt, europcar etc) rentals specifically catering to corp customers with class based models as in you can switch cars within a class regularly and make it 100% tax deductible without writing it off over multiple years etc
I did sell corp GT3s +-0 after driving them for a couple years even with VAT differentials calculated in but not worth it especially today.
