Yes. All carwow dealers will offer the same 0% finance deals advertised by the brands you're interested in.
0% finance is fairly straightforward as the money you borrow when you take delivery of the car is repaid in monthly instalments without any interest applied.
It is generally offered more commonly on Hire Purchase (HP) finance (where you effectively buy the car in instalments over a given period) and less commonly for Personal Contract Purchase (PCP) finance (where you effectively pay the depreciation of the car over the given period you own it).
Generally speaking these 0% HP deals are a good option if you want to own the car at the end of the agreement however you will generally receive less discount upfront when taking this option and the monthly repayments on PCP will usually be lower (even if some interest is being paid).
