2005 Toyota
Convertible
The 2005 Toyota MR2 Spyder is the third-generation MR2, a lightweight two-seat roadster built around a mid-engine, rear-wheel-drive layout. Toyota sold it in the U.S. from 2000 through 2005, making this the final model year for the American market. It pairs a rev-happy 1ZZ-FE 1.8L four-cylinder with a slick 5-speed manual or a sequential manual transmission (SMT), tipping the scales at just under 2,200 lbs — which makes even its modest 138 hp feel punchy. The MR2 Spyder is a pure driver's car. The mid-engine balance, near 50/50 weight distribution, and communicative steering made it one of the most engaging sport convertibles of its era at any price. It's not fast in a straight line by modern standards, but it rewards skilled drivers and rarely punishes them with unexpected drama — unlike its predecessor, snap-oversteer tendencies were largely engineered out. As the last model year for U.S. sales, 2005 examples are increasingly collectible. They're simple enough mechanically that an attentive owner can maintain one without exotic parts costs, but the SMT transmission requires specific knowledge and respect. Parts availability has thinned over 20 years; sourcing some items now requires Japanese domestic market suppliers or specialty vendors.

The 1ZZ-FE is prone to oil consumption. Check the dipstick every fill-up and change oil on the shorter end of the interval to reduce piston ring deposits and extend engine life.
The SMT system uses hydraulic fluid to actuate the clutch and gear changes. Degraded fluid accelerates actuator wear and is the single biggest factor in SMT longevity.
Toyota fills the T-series manual with gear oil at the factory. Fresh fluid keeps synchros smooth, especially important in cold Wisconsin winters where cold fluid thickens.
The 1ZZ-FE responds well to fresh plugs. Worn plugs can worsen oil consumption symptoms and reduce the crisp throttle response that defines this engine.
Seals harden and crack after 20 years, especially with Wisconsin freeze-thaw cycles. Conditioning the rubber seals and fabric top annually prevents leaks and interior water damage.
The MR2 Spyder sits for extended periods in Wisconsin winters. A marginal battery will not recover after long storage. Test and replace proactively if the battery is over 4 years old.
Brake fluid absorbs moisture over time. On a lightweight sports car where braking feel is critical, fresh fluid maintains pedal firmness and prevents corrosion in the ABS system.
Wisconsin road salt is aggressive. The MR2's low ground clearance puts the undercarriage close to spray. Inspect and treat any bare metal or bubbling paint before rust gets into structural areas.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
A well-maintained MR2 Spyder with the 5-speed manual is a relatively affordable sports car to operate day-to-day — simple mechanically, good on fuel, and parts (while harder to find than mainstream Toyotas) are not exotic in price. The big wildcard is the SMT transmission: a failing SMT actuator or clutch can add $1,500–$4,500 to any given year's bill. Budget extra for convertible top maintenance and the reality that many wear items are now 20 years old and approaching replacement together.

Also a Japanese 2-seat RWD roadster from the same era. The S2000 offers more power (240 hp) and a higher-revving engine, but costs more to buy and maintain. Both reward driver skill equally.

The closest direct competitor — lightweight, 2-seat, RWD convertible with strong parts availability and a large enthusiast community. Front-engine vs. mid-engine is the key dynamic difference. Easier to live with and cheaper to maintain than the MR2.
American-market 2-seat RWD roadster at a similar price point. Less refined than the MR2 but more powerful. Parts are now difficult to source and long-term reliability is lower.
No catalog matchShared the Solstice platform; similar trade-offs. Offered a turbocharged Redline version with real performance, but suffers the same parts scarcity and reliability concerns as its Pontiac sibling.
