Still do not understand your maths?
What period and interest rate are we talking about to get £100.
As per Merc's financing tool, I save GBP 100. If I only consider 2K on standalone basis then its coming down to GBP52. However, if I consider the whole loan amount, interest (5.9%) and period (48 months) then as per merc's financing calculator then its making a difference of GBP 100. However, you are right.... somehow GBP 100 number looks high to me as well.Still do not understand your maths?
