PROJECT STREETLINE / BMW E90
Small changes. A car that feels like yours.
Project Streetline keeps the factory character of a BMW E90 while planning considered improvements. Explore its goal, budget and next decision in the example above.
Explore a projectKnow what’s confirmed. See what needs checking.
A useful answer includes its limits. Sources, estimates and unresolved details belong beside the decision.
Source-backed information
Check which vehicle attributes and part numbers the source actually covers.
Owner-provided record
Photos and records tell the story; they are not manufacturer verification.
Estimated total
Shipping and other missing charges stay visible. An incomplete price is not a final total.
Check before purchase
Missing details or conflicting records need a closer look. Fitment and road approval are separate checks.
Built around real workshop questions.
CapCar is in beta. Bring your project and help improve the details. Vehicle coverage, visual references and connected services are still expanding.
Send feedbackWhat is CapCar?
A digital garage for planning changes, finding parts and keeping your vehicle’s maintenance and build history together.
Do I need an account to search for parts?
No. Search publicly, then create an account when you want your own garage.
Will every part be confirmed to fit?
No. Coverage varies. Confirm the vehicle specification, part number and installation requirements before buying.
Can I visualize any modification on my exact car?
Not yet. Concept Studio offers selected visual references. Models and controls vary, and previews do not prove fitment.
Where do I buy the parts?
Retailer purchases are completed on the retailer’s website. CapCar does not take payment for those orders.
Is my garage public?
Your personal garage is private. Review the information before sharing a public passport or publishing a listing.
Do I need a modified car to start?
No. Start with the car you have and the next thing you want to maintain, improve or document.
