I inherited a 2010 Mazda 5 with 103k miles. I have a couple of questions

1. Previous owner was a smoker. Front seats covers have cigaretter burn holes. Need replacement for both seats ( dronts only) .Any suggestion? Not looking to spend a lot. OEM or aftermarket is fine
2. Spare is missing and I'm not comfy drivinng without one. Since I need to buy a replacement , would a full size tire fit or the storage place can accommodate a small size doughnut spare only
3. Head unit is outdated and missing *****. Any suggestion where to find the volume ***** or a suggestion for a more modern head unit?
4 Can the middle row completely collapse like the 3rd row can?
5 Motor mounts. I need new ones because the car vibrates. Not bad but is something you notice. Can I please have a recommendation of what to buy ? OEM or Generic and how big/hard of a job it is to replace said mounts

Thank you

 

1. Local pick n pull type place. Mazda 3 seats should fit. 5 seat covers are hard to find. As are 5 seats.

2. Mazda 3,5 spare should fit. Again, pick n pull your place.

3. Pick n pull or I got one of these;
​​​​​​Android 11 Car Stereo for Mazda 5 2007-2012 with Wireless Apple CarPlay Android Auto,9 inch Touchscreen Car Radio with WiFi,GPS Navigation,Bluetooth,FM/RDS,SWC AUX-in,Dual USB+AHD Backup Camera https://a.co/d/fLhrTXd

I would recommend shopping around before choosing one of these.

4. Go OEM. I went with Amazon ones and put OEM in a year later. I ordered from

Get all thre I had an engine support bar. but some do it with just a floor jack under the engine.

 

I installed a device from these sellers, so far for half a year the radio has been working fine, you can contact them here

 

Did it maintain all the steering wheel controls? It's a little more pricy than a normal head unit swap.
