* Online marketplaces: eBay, Craigslist, and Facebook Marketplace are good places to start. Search using terms like "1989 Buick Riviera wheel cover," "Buick Riviera hubcap," and variations thereof. Be prepared to be patient and possibly pay a premium for a good condition set. Check completed listings to get an idea of pricing.
* Online Buick parts websites: Some websites specialize in classic car parts. These might have NOS (New Old Stock) wheel covers, or used ones. However, these are often more expensive.
* Classic car parts suppliers: Search for classic Buick parts suppliers or those specializing in 80s-era GM vehicles. They may have some leads or contacts within their network.
* Junkyards and salvage yards: This is a more hands-on approach, but you might find a usable wheel cover at a local junkyard that specializes in older vehicles. Be prepared to potentially pay a price per wheel cover.
* Buick car clubs and forums: Connecting with Buick enthusiasts online through forums or clubs may lead you to someone who has a spare or knows where to find one.
Important Considerations:
* Condition: Expect to find some wear and tear on any used wheel cover from that era. Minor scratches or fading are common.
* Pricing: Prices will vary depending on condition and rarity. Be prepared to pay more for a set in excellent shape.
* Authenticity: Be cautious of counterfeit or reproduction parts. Look for details that indicate originality.
Finding the specific wheel cover you're after will require some dedicated searching. Good luck!
