i dont know about you guys but the very best rate you could probably get is to take the money from your flexi housing loan. if you have squeezed your bank, you are paying a good amount below 4% p.a. right now and that beats any offer above 2% from hire purchase for durations of 5 yrs and above. furthermore you can pay back as you can which is a lot nicer than the hire purchase.

personally i never buy cars on loan. but that is a different story.
