BMW 4 Series Convertible review

The 4 Series Convertible is a top-down version of BMW’s popular coupe, itself a three-door version of the even-more popular 3 Series. It mixes premium appeal through eye-catching looks and some of the latest in-car tech with an engaging driving experience that its immediate rivals can’t match. The ability to drop down the fabric roof and get the wind through your hair only adds to the experience, but with the roof up it’s nearly as quiet as a regular coupe.

Don't just take our word for it. We're rated at 4.9/5 on independent reviews website Trustpilot from over 49,994 genuine customer reviews

So simple, the website is easy to use, clear and accurate, I just chose the car and sent an enquiry, then Danny contacted me to confirm my choice. He made it so easy for me, I just sat back while he did the legwork sorting the finance and ordering the car. Once he'd put everything in place, just a few signatures from me and the deal was done, all from the comfort of my armchair. Thanks Danny, we'll definitely be back for our next car

Good communication, good service. Delivery was very efficient and as expected. Handover was professional and friendly.

This is my 6th lease car through Select Car Leasing. The offers are unbeatable, the systems and IT top-of-the-line and the support and customer care provided - in my case by David Shaw - was excellent. Highly recommended company to deal with.
