Hi jusvi2001 and welcome.
I don't know if Peugeot will be prepared to put parking sensors on your car once it's been delivered - you can only ask but a friend of mine did get them put on their car by an independent garage because her hubby got fed up with her constantly bumping the car!. It was a couple of years ago but it wasn't all that expensive (I seem to remember around £100) and they did a really good job.
There are indeed lots of aftermarket sensor kits out there that you can get fitted by an independent garage or even yourself if your comfortable doing so, but I strongly suggest you talk to Peugeot to see if by fitting them you are affecting the warranty of the car. Hopefully, they will OK it and recommend a specific make.
Also, again overlooked by many who fit aftermarket parts, inform your insurance company, as technically, your modifying the car by fitting them. If you ever then have a claim, they could reject it as every insurance contract insists you notify them of any changes to the vehicle.
If parking in your drive is an issue and not sure where to position your car, there is a 'free' method of doing it.
Drive your car in to where you think the rear is off the footpath. Get out and look, if still too far out, look at front to see what space you still have, get back in if necessary and move forward again and recheck until you are in the ideal position.
Then look out your side window and identify something you are dead in line with. It may be a window or tree etc. Thereafter, every time you park the car, as long as you are dead in line with the item you used as your 'mark', then you know the front is safe and the arse of the car isn't over the footpath.
I know lots of folk who use this method very successfully.
