Mercedes-Benz GLB Finance Calculator
Had a GLB dealer finance quote? See what our panel of specialist brokers would charge for the same car, and view comparisons with our free finance calculator.
Prefinance runs the comparison for you: we take the dealer's own finance example for the exact GLB you're looking at and compare it against the best available rate from our panel of specialist finance brokers for that type of vehicle. That turns up savings of up to 30% against dealer finance.
Below are actual Mercedes-Benz GLB finance examples through Prefinance.

What's the difference between PCP and HP on a GLB?
Both are hire purchase agreements in the legal sense; the car isn't yours until the final payment clears, but they split the cost differently. HP spreads the full price, minus your deposit, evenly across the term, so every payment builds toward ownership. PCP, which is what every current GLB example on the page uses, instead sets aside a slice of the price as a Guaranteed (Minimum) Future Value, only due if you decide to keep the car at the end; that's what keeps the monthly figure lower than an equivalent HP deal would be.
Either way, Prefinance's instant comparison rests on one shared assumption: that the lender you're matched with would set the same GFV the dealer did. That's not guaranteed, so treat the monthly payment shown as a close estimate rather than a fixed number.
How does Prefinance work out your savings figure?
Give us the car - a registration number works, so does a make and model, or paste in a link from a dealer site or somewhere like Autotrader, provided that listing shows a finance example. We take the dealer's own quote and set it against the strongest rate our brokers have for that class of vehicle. That comparison assumes you'd land the specialist broker's best rate, which comes down to your own credit standing, and that the dealer selling the car is FCA authorised. Every comparison you run stays saved to your account, so there's no need to redo one later.
Representative APR is the rate at least 51 in every 100 customers a lender approves actually receive, or better. The specialist brokers have proven competitive on GLBs going by the real quotes above. What you'd personally save comes down to your choice of car and circumstances.
What changes the exact rate you're offered?
Your credit score has the biggest bearing, but deposit size and the car's age can both move the number too, as the table shows; the two 30,355-mile rows make that obvious, with an extra £3,438 of deposit trimming over £83 off the monthly payment on the same car. A longer term usually brings the monthly cost down, though the total interest paid is higher.
There's also a commercial reality worth naming: arranging finance isn't done for free, and a portion of what you pay reflects commission built into the deal on both the dealer's and the broker's side. We get paid from either there broker's commission or on a fixed fee per lead we send them.
Worth checking before you apply
Make sure the deposit and mileage in your comparison match what the dealer's actually quoting - the deposit's editable, but get anything else wrong and the result skews.
If you're weighing a bigger deposit against a smaller one on the same car, look at how much it actually moves the monthly payment, not just whether you can afford to put more down.
Check what happens to your monthly payment if your matched lender's GFV comes in different from the dealer's - don't take it for granted that it'll match exactly.
Read the broker's full quote before signing anything - it holds the real figures for your deal, not the illustrative ones shown here.
If the same car appears more than once with a different price, deposit or term, check the listing on the vehicle's own page before deciding which figures are current.
Running the comparison on your specific car is the only way to know for certain if the dealer's offer is competitive. If it is, it's could be convenient to go with their deal. If our brokers can save you money, then that could be a better choice.
Comparisons are free, and applying is free. A full application gets you referred to the most suitable broker for you, and they will give you the final quote. We only act as a technology service to help you work out the payments easily and to refer you to an appropriate lender.
