Hi Amar,
Welcome to TAI!
I too have a M800 Type1. In my opinion these are the things you can try in your car
Replace Bumpers (Use M800 Type1 only) - 2K (max)
Replace all door handles & rollers with M800 Type 2 - 400/- approx
Replace all wheel rims - costs 750each (Approx) MGP price
Check your door hinges for excess play (let me know if you need any help in finding the condition of them), if yes they cost 80rupees approx each
Vinyl Mat for whole car floor - 1.2K max (Choose lighter colours)
Door pads (7pieces) - Type 1 is 600approx, type 2 is almost similarly priced
Headlamps + Tail Lamps + fender Indicators - 1000max (all lumax, except tail lamp)
Mechanical parts replacements (only the must ones mentioned here)
Radiator Hose kit - 170 (3pieces)
Clutch Cable - 150 (MGP only, NEVER buy REMSONS brand) max
throttle cable - xxx (no idea, Varun can help here)
Brake Booster kit - 3370/- (KBX Brand)
Brake Disc Pads - 150/- (Pair - KBX/Bosch/delphi)
Fuel Filter + Oil filter - 200max
Fuel pipe (pink tube) that connects the fuel filter etc - 20Rs.

Type2 Wiper arms + Bosch wiper blades - 500/- approx
Ignition coil wires kit - Delphi brand - 270/-
100/90 Headlamp wiring kit (with relay): Roots/Hella/Bosch = 700 (max)
100/90 Bulbs - Philips - 200Rs. max
Fluids Replacement:
Engine Oil: 3Ltrs - 15W40, Castrol/Shell
Brake Oil: company says use DOT 3, Me, Varun are using DOT 4
Distilled Water for battery: 20Rs/ltr (one litre is enough, available at most battery shops)
Whatever distilled water is remaning use it in windshield wiper tank.
Your problems & possible solutions:
Dirty Interiors: Complete refurbishment of interiors (Seatcover+new sponge+vinyl mat+ floor mats) - 5 to 6K easily (try matching door pad colors to steering wheel & seat covers)
Brakes are scary: Brake Booster can solve this to some extent
Rusted body: Hmmm, this is something very costly to deal with. Ideal solution is complete repaint (costs 16K to 25K) including tinker work. You can do it later too. Watch out for cracks/holes/bubbles in the body.
Steering shaking: Steering column (or related parts) might be loose - Jarpickle & Varun can help here.
More Noise : Floor mats + serviced engine (new oil) etc can make a difference here.
Personal Touches:
Repaint the Airfilter box (Black/Chrome)
Mesh Grill (DIY)
Replacing these parts should be a DIY - Door pads, floor mats, carpet, bumper, tail lamps etc You will get to know your car better.
Tyres & RIms: There are experts here who can help you out with the best sizes, brands & other options. Stock tyre (factory fit) size is 145/70 R12
Hope this helps.
