Should I take my cbt at 16 and wait til I'm 17 to buy my first bike?

Hi, I'm 16yr old and I really want to get my own motorbike/moped(I know the difference so please don't explain).
I have around 10months experience on a 125 Honda cb so I'm comfortable with changing gears.
I have spent around 3 months looking around for a 50cc moped(preferably a sports design) but most of them are around £1000 which is almost the same as a 125.
My question to you experienced riders is… Should I pass my cbt now(at 16) and wait until I'm 17 to buy a 125?
Any other answers are welcome. Thanks

Added (1). I'm in the UK. Thanks for your responses, a car is too expensive for me. I'm looking to spend under £1000 if possible, don't mind going to £1200 max

Depends, I started riding at 21 and spent very little time on a 125cc before going for a 600cc on passing my test.

It's all up to you but if I was to do it all again I would wait till I was 24 and just buy a new big bike on passing the main test.

However if I needed transport so bad then I would buy something at 17 and renew CBT every 2 years.

Yeah pass cbt now, get a lovely second hand 50cc enduro 100% road legal.

Get a car when you're 17.

I would get a 50cc, purely for the experince and imnporvement in roadcraft, and learning how to top up oil, tighten the cahin and stuff. Just, please, don't cone on here asking how to make it quicker. Don't forget to factor in insuarnce csts (that guy who told you to get a car forgot that!). My first 50cc (BSA Brigand) was £70. My first 125 (Suzuki GP) was £400. Okjay, thais was back in the ealy 90s but take someone along who know about bikes. If you were near me I'd take you.

Forget the Moped as you would still have to Pass a A1 CBT before you could ride a 125.
When you get your Full A1 Licence you will get the Full Moped as well.
If you get your Full Car Licence you only have to Pass the Moped CBT to get your Full Moped Licence.
