All bolts and fitting on my car are rusted through. Anybody thought of using stainless steel bolts instead? The pros are obvious, are there any problems stainless would cause, apart from higher cost?

Yeah, in high tensile application a stainless steel bolt will not be strong enough. There's a thread on here somewhere about this.

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

Also stainless into alloy causes corrosion and the bolts will never come undone again.

Use waterproof grease upon assembly every time you work on it and eventually, like me you'll have had the car completely apart and will have done this everywhere.
Obviously use new standard bolts when you first strip each part of the car.

The normal stainless bolts on Ebay are A2 grade stainless and less strong than carbon steel grade 8.8 that most good quality bolts are made from.
Stainless grade A4 is getting there but and it is a big but.
Most normal available Stainless bolts do not have the give that carbon steel has and tend to brake rather than having that touch of elasticity in let's say a suspension member getting a shock loading after hitting a deep pot hole.
The carbon steels gets it and carries on the stainless has a tendency to fail.
Therefore do not use stainless in these applications and of course the similar metal corrosion issues.
